1. An optical element driving mechanism, comprising:
a fixed assembly;
a movable assembly, configured to be connected to an optical element, wherein the movable assembly is movable relative to the fixed assembly, and the optical element has an optical axis;
a driving assembly, configured to drive the movable assembly to move relative to the fixed assembly; and
wherein the fixed assembly includes a base, the base has a first side wall, the movable assembly has a winding structure, and when viewed in a second direction perpendicular to the optical axis, the winding structure overlaps the first side wall;
wherein the optical element driving mechanism further includes a first elastic member connected to the fixed assembly and the movable assembly, the first elastic member includes four separate spring sheets, and when viewed along the optical axis, these spring sheets are rotationally symmetrical.
